Hi everyone! i have a scenarion here.
I have a grid and i used GridTemplateColumn and used the the input object for the binding.

<telerik:GridTemplateColumn AllowFiltering="false" UniqueName="Selected">
<ItemStyle Width="1%" VerticalAlign="Top"></ItemStyle>
        <ItemTemplate>
                <input type="radio" name="rbStatisticalValue" value='<%# CastValue(DataBinder.Eval(Container.DataItem, "ID")) %>'
                        <%# SetCheckedStatusForRadioBtn(Convert.ToBoolean(DataBinder.Eval(Container.DataItem, "Selected"))) %>/>
</ItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn AllowFiltering="false" UniqueName="ListOrder">
     <HeaderTemplate>List Order</HeaderTemplate>
     <ItemStyle Width="1%" VerticalAlign="Top"></ItemStyle>
     <ItemTemplate>
          <input type="text" value='<%# CastValue(DataBinder.Eval(Container.DataItem, "ListOrder"))%>' readonly="readonly"  maxlength="3"/>
     </ItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn AllowFiltering="false" UniqueName="Title">
     <HeaderTemplate>Options</HeaderTemplate>
     <ItemStyle Width="1%" VerticalAlign="Top"></ItemStyle>
     <ItemTemplate>
          <input type="text" value='<%# CastValue(DataBinder.Eval(Container.DataItem, "Title"))%>'/>
     </ItemTemplate>
</telerik:GridTemplateColumn>

when i click on the Add New Record on the grid, i got this error
"Object cannot be cast from DBNull to other types"

I cannot figure out whats causing this error...
